3.3.9 Installing the measuring sensors Prosonic Flow W
(dual path Insertion version)
1. Determine the installation area (e) on the pipe section:
– Installation location: Page 14
– Inlet/outlet run: Page 16
– Space required by the measuring point: approx. 1 x pipe diameter.
2. Draw the middle line on the pipe at the mounting location.
Fig. 32: Installing the dual path measuring sensors, steps 1 and 2
3. At the mounting location, pull the sensor holder to one side the length of arc (b) from
the middle line. Usually, the arc length is taken as approx. 1/12 of the pipe
circumference. Indicate the first drillhole (drillhole diameter approx. 81...82 mm).
! Note!
Make the lines longer than the drillhole!
4. Drill the first hole, e.g. with a plasma cutter. If the wall thickness of the pipe is
unknown, measure it at this point.

5. Use the “Sensor installation” Quick Setup to determine the sensor distance
(distance between the two drillholes) and the arc length between the sensors of the
measuring groups. Run the Quick Setup as explained on Page 82. The sensor
distance is displayed in the “Sensor distance” function (6886) and the arc length in
the “Arc length” function (6887).
! Note!
– To run the “Sensor Installation” Quick Setup, the transmitter must have a local
display and be installed and connected to the power supply.
– In the case of transmitters without a local display, the value can be determined as
explained on Page 86 ff.
